Meaning & origin
Joslyn is a modern spelling variant of the medieval name Jocelyn, which entered English after the Norman Conquest from Old French Joscelin. The name's ultimate root is the Germanic Gautselin, a diminutive referencing the Gauts, an ancient tribe connected to the Geats and Goths. Joslyn first appeared on U.S. records in 1930 but saw its peak popularity in 2010, reaching rank 2,719 in 2025 with a frequency of 1 in 25,512. Its trajectory has been falling since 2011, with top usage in Tennessee and Ohio. The name's similarity to other modern -lyn composites like Kailyn and Jaelyn reflects a broader trend in feminine name styling.
